Abstract
This research introduces the manufacturing process of the metal-framework of one of the maxillary partial dentures, the “obturator”, using milling wax-blocks, for patients with palate loss due to oral cancer. It explains the protocol of taking the patient’s oral impression, prep-aration of a working cast, scanning, designing using a computer-aided design program, in-vesting the milling wax-blocks, and completing the obturator. This method does not follow the traditional wax and agar process thereby reducing the errors arising during the manu-facturing process and decreasing the time, material, and labor required. Moreover, the re-tention, stability, and compatibility of the metal framework were observed to be high in both the working cast and oral cavity.
